“Classical” vs. “Acoustic” Guitars

by Dave Belcher

If you’re new to guitar or have only ever played one style of guitar before, you might find yourself asking, What are the actual differences between an acoustic and a classical guitar and which one is right for me? It’s pretty easy to discern the difference between electric guitars and acoustics and classicals: while you can indeed get acoustics and classicals with electronics on board designed so you can plug them into an amp, an electric is always . . . well, electric! But what are the main differences between an acoustic and a classical guitar? We’ll clear that up and hopefully give you an idea of what might fit you best.


The main and most palpable difference is that acoustic guitars use “steel” strings while classicals use “nylon.” (I’ve put inverted quote marks around those because the material is not always steel or nylon, but that’s still usually what we call them.) And there is a very noticeable difference in how those strings sound. Even if you were to put steel strings on a classical guitar (which you should never do as it will damage the instrument!) that classical guitar would sound very different than it would with its usual nylon strings. While acoustic strings are made of much harder material (and so require a lot more tension, which is why you also shouldn’t put nylon strings on your acoustic), classical strings are usually thicker. Both can leave callouses on your fingers after long periods of playing, but acoustics will certainly be harder on your fingers.

Neck size

Acoustic guitars also have much narrower necks than do classicals. Classical guitars’ wide neck profile allows for accurate placement of all four fingers on the fretboard at once, while the narrower acoustic neck is easier for moving chord shapes. In general most classical necks are also not as thick as acoustic necks.

Fingerboard shape

Acoustics also have radiused fingerboards while classical fingerboards are most often flat. (Incidentally, this is why you won’t be able to use your acoustic capo on a classical guitar, because acoustic capos are rounded to match the radius of the fingerboard while classicals are flat . . . you’ll get a buzz on classicals with an acoustic capo.)

Body size/shape

While you can find some small-bodied acoustic guitars (such as “folk” or “parlor” acoustics), in general acoustic guitars have much bigger bodies than their classical counterparts. The sides are usually thicker, the back is rounded, and the “waist” of the guitar is usually wider. The most common model of acoustic guitar in fact is called the “dreadnought”! This usually also means that acoustics are a bit heavier than classicals. Most concert classical guitars are full-bodied instruments, while many acoustic guitars have “cutaways” that make access to the upper frets much easier. (To accommodate for the problem of lack of access to the upper frets on classical guitars, many modern luthiers, especially Thomas Humphrey, pioneered elevated fingerboards . . . though even Stauffer was doing this on some guitars in the nineteenth century.)

Fret Markers

If you’ve played much on acoustic or electric guitars you may notice that there are dots in the middle of the fingerboard to help guide you where you are on the frets. Classical guitars sometimes do have dots at the seventh and twelfth frets (and in some exceptions elsewhere) on the upper side of the neck, but in general they usually do not have any fret markers on the fingerboard itself.


Another big difference between classicals and acoustics is at the bridge, where you fasten the end of the strings next to the soundhole. On an acoustic guitar strings have little balls on the end of the strings, which are held in place with bridge pins. On a classical, however, the strings are tied around the bridge, making for a very different method of changing strings.

Headstock/tuning machines

Likewise, at the other end where the strings attach to the headstock, classicals typically use slotted headstocks with in-line tuning machines while acoustics usually have individual tuning machines that stick up through the headstock. This will mean, once again, that changing strings at the headstock will require a different method on a classical than it will on an acoustic.


Because of the differences in string type and tension, acoustic guitars are generally much louder instruments. While modern building techniques have vastly improved the volume capability of modern classical guitars, they are generally quieter instruments.

Right hand

Finally, in general there is a different approach to the use of the right hand between the two types of guitar. Very often acoustic players will use either a pick (plectrum) or finger picks, while classical players use either fingernails or the flesh of their fingers. On the other hand, the approach to the right hand will in many ways be dictated by the style of the music, and while most would not use a pick on a classical guitar (and almost never for classical music on the guitar) you may find many acoustic players who use fingernails on their right hand to pluck.


But which is right for you? Ultimately it all comes down to your style, what kind of music you want to play, and what sort of sound you want to create. Acoustics and classicals have very different characteristics and each will yield very different musical results. Pick the tool that best suits the music you want to create.

    Great article, Dave!

    I discovered one more difference when I made the switch to classical: the amount of money that I paid for the steel string guitar of my dreams was almost enough for an entry level student model classical guitar.

    Thanks as always,

      Ha! Yeah, you can definitely get expensive acoustic guitars but the luthier-made classicals are generally more expensive. Thanks for the comment, Mark!

    Thank you Dave. This was illuminating.
    I nearly panicked when I read that putting steel strings on a classical guitar will damage the instrument. I ran to my guitar because I recalled that the strings I use (Savarez HT Classic) were wound and seemed metalic for the 3 lower strings. But maybe that would explain the buzzing and the tinny high E sound, I thought. Well, I see that they are “wound on stabilon” (what ever that is) and that they are made for classic guitars so at least there is no potential damage. However you made me wonder if there would be a better string for me to use. I use these on the recommendation of my first teacher. Any advise and recommendations would be welcome.

      Hi Cindy,

      Yes, it can get confusing because different string manufacturers will use different materials as well as different terms to describe those materials. There’s “silverplated” or “steel wound nylon core” and other such terms used but so long as the pack is specifically for a nylon-string classical guitar you’ll be A-OK! Many use Savarez and love them. I prefer D’Addario but every person is different and in many ways strings are very subjective.

      Buzzing is likely a result of action on the guitar but could also be a result of frets that need leveling. A luthier could help you by taking a look to tell you for sure. The tinny high E string could be from a number of different things, including the guitar itself in its design, your nails, angle of attack on the string, etc. Hope some of this is helpful.

    Hello there.
    I am new to playing guitar, and i was wondering if classical guitars would be good for country music, I’m into Brad Paisley kinda like music, and classics like Kenny Rogers and John Denver. I know it sounds different, but are the tones going to be alike? And does the chords differ between Classicals and Acoustics?

      Hi Suhayb,

      Acoustic steel string would fit that genre better. While the tuning of the strings is the same (and so chords will be the same across the two guitars) the sound of the acoustic fits better for country music.

        Don’t tell that to Willie Nelson. His guitar, Trigger, is a classical guitar

          Good point! But you generally won’t hear too many classical guitars on Brad Paisley, Kenny Rogers, or John Denver tunes.

    Hi there!
    Thank you for the explanation!
    My question is – if I learn classical guitar playing style and repertoire using acoustic guitar – is the only problem a different sound or I do something wrong or miss something important that way? Of course I am planning to buy a classical guitar as well but I just wonder wether it is critical or not.

    • Dave Belcher January 7, 2019 at 8:15 am - Reply

      Hi Ieva,

      Yes, there will be a difference in sound, but because of the difference in string width (because of the narrower neck) and the difference in string type (“steel” vs. nylon) it will take adjustment when you want to switch between one and the other (plus the harder strings on acoustic will tear up your nails much more quickly!). So while you would not be doing anything wrong at all, it will be easier to build up “muscle memory” especially for the right hand if you stick with one instrument. With that said, there are many great classical players who also play steel-string and switch back and forth quite effectively — but most of these players, like Michael Chapdelaine, have built up their technique over decades and usually had built up classical technique before playing acoustic. Hope this helps.

    There is yet another difference. No pickguard.

    Don’t really need one on a classical guitar.

      Yes, great point, Bill! However, flamenco guitars have “tap plates” that serve a somewhat similar function and many classical guitarists have added them to the tops of their guitars in the form of a cling-on plastic sheet.
